Shown in the figure below is an RC circuit. At t=0, the capacitor already contains a charge and as a result has a voltage of 7.30 Volts. The resistor has R = 5725 N, and the capacitor has C = 3.81e-06 Farads. At t=0, the switch is closed. ww switch Enter a number. Determine the time constant of the circuit, T= x seconds Fill in the table of formulas below. Use numerical values for the "max" column and a formula for the "form" column: max form Qcap(t) |× c -() e X V e ()- Vcap(t) Vres(t) e X A е -() Ires(t) • Determine the current at t=3.23e-02 seconds. X Amps NOTE: The entries for "max" are numerical. The entries for "form" leave out the leading coefficient. Here are examples: If the answer was: max: form: Q(t) = 12 sin(@ot) 12 sin(@t) V(t) 45 log(t/t) 45 log(t/t)
